Application filed October 11, 1922. Serial No. 593,717.

To all whom it may concern:

Be it known that I, ARTHUR G. HATCH, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Concrete Walls, ofwhich the following is a specification.

This invention relates to a new and improved concrete wall constructionand more particularly to a wall provided with securing or binding blockswhich aid in maintaining the stability of the wall.

In certain types of concrete wall construction now in general use, thewall is formed by oppositely faced blocks forming in effect two adjacentwalls. In some such constructions, the walls are bonded by theengagement of integral flanges upon the blocks in opposed series. A wallof this character, as generally designed and constructed, contains anexcess of compressive strength over that normally required. Thisstrength is due to the use of sufficient material to provide thenecessary lateral stability in the wall. In order to provide increasedstability, it is desirable to place'the adjacent walls at a greaterdistance apart, thusgiving the walla greater effective thickness. Insuch cases it is unnecessary to make the individual blocks of greaterthickness or to extend their flanges due to their excess of compressivestrength. It is further undesirable to make different forms of blocksfor walls of differ ent thickness since this entails the duplication ofthe necessary forms and apparatus used in making the blocks and arequirement for keeping a larger stock to include the various forms. Itis also unnecessary to bond the walls by flanges throughout the lengthof the block since adequate lateral bond can be secured by lessmaterial. I

It is an object of the present invention to provide a wall constructionhaving means adapted to secure and bind together adjacent walls.

It is a further object to provide a con struction of this characteradapted to be readily varied for walls of differing thickness.

It is also an object to provide securing means in such walls adaptedalso to formmeans for securing inner wall surfaces to the concrete wall.

Other and further objects will appear as the description proceeds.

I have illustrated certain preferred embodiments of my invention in theaccompanying drawings, in which Figure 1 is a plan View of a portion ofthe wall constructed according to the present invention;

Figure 2 is a section taken on line 22 of Figure 1; i

Figure 3 is a view similar to Figure 1 showing a modified form ofconstruction; Figure '4 is an inner face view of the wall of F i ure 3,the inner sheathing being remove I Figure 5 is a view similar to Figure1 showing a further modification;

- Figure 6 is a view similar to Figure 1 showing a still furthermodification;

Figure 7 is an inner face view of Figure 6, the inner sheathing beingremoved,

Figure 8 is a section taken on line 88 of Figure 7.

Referring now to the form of construction shown in Figure 1, the wallcomprises two adjacent walls A and B. These walls are composed of wallblocks/11 which, as shown in Figure 2,'are formed'upon their innerfaceswith recesses 12 formed by ribs 13 and flanges 14. Asshown in Figurel,the blocks formingthe outer wall are provided with. a plain face whilethose forming the inner wall are provided with the lugs or ribs 15 towhich is secured the inner wall sheathing 1 6. The ends ofthe blocks.are formed with the vertically extending recesses 17. Thesecuringmembers 18 extend transversely between the walls A and B and bind themtogether. These members 18 are provided with edges 19 fitting within there cess formed by adjacent grooves 17. The

members 18 are provided with longitudinally extending metalreinforcement 20.

In the form of construction shown in Figures 3 and 4, the wall consistsof the opposed walls C and D. The outer wall is formed of blocks 21having their ends formed with grooves 22, the grooves upon adjacentblocks together forming a recess having re-entrant angles. The blocks 23forming the outer wall are shorter than the blocks 21, and their endsare spaced apart. The binding or se curing blocks 24 are provided at oneend with a dovetail portion 25 adapted to fit in the recess formed bythe grooves 22. The opposite end of the blocks 24 extend through betweenadjacent ends of blocks 23. The i blocks 24 are provided with metalreinforcement ribs, as shown.

The blocks 23 are provided with ribs or lugs 27 adapted to bear againstthe inner wall sheathing and the blocks 24 preferably extend flush withthe face of these ribs 27 The blocks 24 or the ribs 27 or both may beformed of nailable concrete so that the inner sheathing may be directlysecured thereto.

The form of construction Shown in Figure 5 is similar to that justdescribed with the exception that the intermediate portion 30 of thesecuring blocks and the dovetail portion 31 of' these blocks. is reducedin thickness as shown in Figure This reduces the size of the recessnecessary in the outer wall blocks.

In the form of construction shown in Figures 6 to 8, the wall comprisestwo walls E and F. As best shown in Figure 8, the blocks 35 comprisingthe outer wall and blocks 36 comprising the inner wall are each providedwith flanges upon their upper and lower sides which flanges diifer inlateral extent. This permits a bond between walls to be secured byoverlapping the flanges as clearly shown in Figure 8. In thisconstruction the inner blocks 36 are of less length than the outerblocks 35 as shown in Figure 6. The securing blocks 37 are placedbetween the ends of adjacent blocks 36. These blocks 37 are preferablyformed ofnailable concrete and extend out beyond the face of blocks 36and flush with the. face of the ribs 38 carried by such Obviously theforms of construction shown in Figures 1 to 5 permit walls to be madeof..differing thickness without variation in the size and constructionof the wall blocks simply by varying the length of the transversebinding blocks. By placing these binding blocks as shown in ldligures 3,5 and 6 so as to extend beyond the wall face and serve as nailingsupports for the ir ier wall sheathing; it becomes unnecessary toprovide lugs upon the wall differing in material from the main body ofthe wall blocks. That is, the binding :blocks may be made of nailableconcrete while the wall blocks are entirely of other concrete. In suchcase-the wall block ribs serveas spacingsupports but will not receiveany nails. The transverse binding blocks are provided with metalreinforcing which reinforcing blocks.

serves to take up the tensile stress and per mjt the blocks themselvesto be of comparatively small area.

I have shown certain preferred embodiments of my invention but it isobviously capable of other and varied embodiments adapted for differentpurposes and constructions.

I claim:

1. Wall construction comprising adjacent walls formed of blocks andsupplemental securing blocks extending between the adj acent walls andhaving portions extending beyond the wall face, said extending portionsbeing formed of nailable concrete.

2. lVall construction comprising adjacent walls formed of blocks andsupplemental securing blocks extending between the adjacent wallsand'having portions extending beyond the wall face said securing blocksbeing further provided with portions ex tending within re-entrant anglesupon the wall blocks whereby they secure the acent walls together.

W allconstruction comprising adjacent walls formed of blocks and supplementalsecuring blocks connecting the adjacent walls, the securing blockshaving portions fitting Wllllllll'tlll contour of one wall the end ofthe securmg block being covered by the wall :blocks, and having itSopposite end extending through and beyond the other wall, the extendingportion being fol-med of nailable concrete.

5.
